The emails declassified as of the end of January, released after a FOIA request from Buzzfeed reporter Jason Leopold, follow the late December release of another tranche of messages that were stored on the backup program Abedin shared with her husband, disgraced New York congressman Anthony Weiner.

Clinton's use of a private email server for official business including some classified information became a major focus of her critics during the campaign, though then FBI Director James Comey said that she her actions were "extremely careless" but did not rise to the level of a crime.

Comey announced in a letter to Congress shortly before the 2016 election that investigators were looking into the server again after emails were found on a laptop during the sexting probe into disgraced New York congressman Anthony Weiner, who is married to Abedin.

President Trump, who says that the investigation into his campaign’s potential collusion with Russia is a “witch hunt,” has also berated the FBI for not pushing for a Clinton prosecution.
